CCJ editors recently visited one such plant in the California oil patch and discussed controls-related experience with the plant manager (PM). Evidence of this manager’s I&C chops were additionally revealed in a 1991 ASME paper he […]

Electric fuel control valve streamlines plant operations

Like some other vintage Frame 6B-powered cogen plants, this facility in the California oil patch, recently visited by CCJ editors, was plagued with fuel-gas valve problems, usually requiring at least a man-shift’s worth of work each outage to disassemble, clean seats/plugs, and reassemble. Sometimes an outage would have to be taken if leakage was indicated […]
